Missing Fingerprints

According to the climate models used by the IPCC and other climate alarmists, the mid-troposphere should be rapidly warming if increasing CO2 is a forcing for warming. If this warming does not occur roughly as predicted then the climate models are proved to be worse than useless. The ‘fingerprint’ evidence of anthropogenic warming due to increasing CO2 is predicted to be a pronounced ‘hotspot’ in the troposphere between latitudes 30N and 30S (which comprises exactly half the surface of the earth) at a height of around 10km (cruising altitude for jet planes), see below for expected change during the 20th century from the latest IPCC report. Obviously, if anthropogenic global warming is going to ‘take off’ this century, then this hotspot will be considerably more pronounced in the 21st century. The models used by the IPCC predict warming of the troposphere some 12 km high at the rate of 4-5 degrees per century for this century. This hotspot is absolutely essential if the climate models have any validity at all.

Other climate models predict the same thing: here are four others (showing effect of doubling of CO2). Note that all predict a pronounced tropospheric ‘hotspot’ 10km up and between the tropics.

However, this hotspot has never been found – if it had been, we would certainly have heard about it, shouted from the rooftops by the climate alarmists. This missing fingerprint that they are peculiarly silent about (for obvious reasons) invalidates their models. It shows their models and their whole hypotheses to be trash. Below are the actual measured anomalies, and it is evident that not the slightest hotspot can be found.
